i Similar letters denote similar parts.

A are the type-operating keys. These typeoperating keys have two vertical arms, ct a, in the same vertical plane, and these arms are connected together by the rod or bar a2. The arms a of the iinger-keys are arranged in any desired manner upon the operating-board, and are shown in plan view, Fig. 13, arranged in arcs of circles. The arms a of the typeoperating keys A are preferably constructed so that they shall point to a common center. The bars a2, connecting the two arms of the type-operating keys A, are all of the same length, or approximately so, and parallel to each other; but the arms a of the type-operating keys A are attached to these connecting-arms a2 at different distances from the arms a', as is shown in Figs. 13 and 30. The extension of the connecting bar or rod beyond the arm a is for the purpose of operating the spacing mechanism and the ribbon-operating bar at about the same point.

The arm a is constructed as shown in Fig. 32, and in the orifice a3, which is cut out of the surface, is placed a spiral spring, a4, said spiral spring being fixed at one end to the plate b, Fig. 1,and the other end to the iingerkey A, Figs. 1 and 30. The type-bar a5, having the desired Jrype at its lower end, is connected with the type-operating key A by means of the arm a, Figs. 1. and `50, of the type-operating key by being pivoted in the screw a7, so that it is loosely and not rigidly joined thereto. This type-operating key A is preferably constructed by stamping the vertical arm a and the rod or bar a2 in a single piece of metal, and the vertical bar a is connected to said rod or bar u? at .the desired point.

The type-bar hanger as, having a circular guide, .f1/2, is secured to the bar B, Figs. 1 and 13, by the screw h4, and in this hanger and guide the type-bar is swung and guided during its movement to and from its impact point. Vhen the operator presses the typeoperating' key, the type-bar is caused to move in an arc of a circle guided by the circular slot a, 1, 30, and 32, by the pivot or IOO guide of the hanger, so as to impinge upon the platen at the proper point. The spring (14. hereinbetore mentioiied, assists the type-bar and ty] )eoperatin key in returning to their normal position when thetypesoperating key is released. The tyljieoperating keys are guided during this olieration by the orifices in plates b b, Figs. l and Lt'i.

In liig. l,(.l represents the platen, havingthe pressureroller c, between which and the platen the paper rests. I) represents the pla ten-carrier. Th is platen-carri er is attached to the rods e of the main frame F ot the machine by means ot? the bearings also that the i)laten-carrier can have alateral motion along the rods c, but is held tast and prevented by said bearings trom moving up and oit ol said main trame. The rods care secured to a pivotal portion ot the main iran1e,to be hereinat ter described.

A portion, E', Figs. i4 and 20, ot.' the main frame E is pivoted at e2, so that that portion. oll the main trame can have a swinging motion. The platen-carrier l) has attached to it a ctmtact-arm, d', which .rests agail'lst the rack carrying platen-carrier-operating frame (fr. This travels along the rod g, (a portion oi' the main frame shown in ligs. 'l and il.)

A rack, g', is attached to the frame G by means ot' screws g2 in slotted holes g/: in said rack, so that the vertical movement may be given to this rack g by loosening the screws, the purpose ot which will be hereinafter stated. The rack g works into the gear f1'1 oi' the spring-impelhsl actuatingdru1n F. The spring in this drum causes the drum and gear to revolve, driving the rack forward, and this forward movement ot' the rack carries with it the :trame G, which in turn moves the platencarrier I.) it'orward. The rack v(,f is guided in the bearings or lugs e, Figs. il. and 20, ol the main trameE. The arms (/are so constructed that when the portion E et' the main trame and the spring-actuated drum at any time,

.E is swung, as heretofore described, the arms d are moved inthe arc ol. a circle the center g ot which is el, and are always engaged or in contact with the trame G.

The arm may be attached to the rack carrying the carrier-operating iframe without aii'ecting the result or method ot operation.

The movement oi the drum is coi'ltrolled in such a manner that the platen -carrier is l caused normally to travel a distance equal to .1 the distance desired between letters, and this l accomplished by the following' n'leans: The

trame f has a 'recilln'oeating motion, by which the dogs j andjl are alternately engaged and disengaged. These movements are actuated by the spacingframe H. (Shown in Figs. 1,13, and 17.) This spaeing-i` rame has its front and rear ends 71 parallel and in straight lines. This spacingsirame is suliiported by a pivotal connection with the support It', and is normally held in position by the spring 71.2, Figs. l and 13, which spring also retains the dogf2 normally out of connection with the ratchet f3, as shown in Fig. l. The sifiacing't'rame is connected to the vertical reciproeating slid ing lramef by mean s ot the biturcated. projection 7L, Figs. l, 125, and 117, at or near the center ot the rear end et the si'iaeing-t'rame in which the lower end of the tramef rests.

The coimecting-rod (iff ot: the type-operating key, as has heretofore been stated, made of sufficient length that its outer end will pro ject beyond the outer end ot' the spacingt'rame. Then the operator depresses one ot the type-operating keys, the connecting-rod (l2 depresses the spaeii'ig-irame 7L, which, acting upon the Vframej, releases the upper dog, j", causing the lower degni, to enter into the ratchet-tooth oi.` the drum. Yfhen the operator .releases the typo-i perating key, t-he dog f2 is released and the drum revolves the distance equal to the (listz'mce between the ratehet-teeth, or the spaceol one letter. The s] ning h2 causes the spacing-trame and the reciprocating' vertical sliding trame f to return to their normal position. The springfH on the rod ff forces the rod a distance governed by the position olf the lugf on said rod, which is normally set a distance equal to the distance between the ratcllet-teeth, and said dog f falls into the next ratchet-tooth from that; which it formerly occullied, and is In'evented, when operated by the drum,t'r nn moving more than its proper distance by the shoulder t on the rod]V In order to increase the power ol' the spring the screws g2 of the rack gj are loosened and the rack moved u p vertically ott oi. the gear ing on the drum by lmeans ot' the slots f/i in the rack, hereinbefore mentioned. The drum is then released from the rack, and the tension of the slfiringin the spring-aetuated drum is increased by revolving the drum by hand, or, preferably, by moving the rack, released Yfrom the gearing on the drum, any distance ot its travel forward and then returning the rack into connection with the gearing on the drum and pushing the cs'trrier and the rack. connected with the drum back to their initial. position, thus increasiilg the tension ot' the i spring, the dogf ]j)rev mting the drum from revolving when released ti'rom the rack. When the .rack is moved ot't' the geariii gon the drum, as has just been described, the tension ol.' the spring ot the spring-actuated drum will be decreased by operating either any ot the type operating keys or the spacing-key.

Located at the iront ot' the machine is a spaceskey, A. This key (shown in Figs. `l and.

IOO

ITO

13) is an ordinary plunger, having a wing, (v10, (if the key bc square this may be discarded,) to prevent .its rotating. A spring surrounds the barrel of this key to hold it normally in position. The foot of this spacekey rests upon one of the fingers a, projecting from the end of the spacing-frame. The spacing-key A is held in the frame a8, the upper end of which is secured to the upper plate, l), by the set-screw a7, and the lower end is guided on the wire a", to which it may also be secured by a set-screw, ifdesired. Then it is desired to nieve the spacing-key, the set-screw a7 is released and the frame as, with the key A, is moved to the desired position on the machine. Then it is desired to move the spacing-key A within the surface of the plate l), especially at the extreme right or left of said plate, then the pin b3 can be withdrawn (said pin limits the upward movement of the spacing-key) and key and spring removed and replaced in one of the orifices uw, suitably formed in the plates l) and b and having` fingers a of the spacing-frame adjacent thereto, when necessary; but where the orifice is in such a position that the key when placed therein strikes the spacingframe itself no finger is necessary.

When it is desired to move the platen-carrier forward the whole length of its travel, or any distance greater than one letter, it is accomplished in the following manner: The dog f2 is so attached to the frame f that it has a vertical movement, being retained in its normal condition by the spring fw, Fig. l. The spacing-framev is constructed as shown in Fig, l, and the complete action of a type-operating-key or the spacing-key moves it a sufficient distance to cause the dog f2 to engage the ratchet-wheel f3, as heretofore described, and disengage the dog f J' but if the operator forces a further movement of the space-frame by pressure on one of the fingers a, preferably the center finger, the frame f is caused to rise higher, and aprojectiom-f, upon the reciprocating frame strikes the lever j, pivoted at f20 upon the main frame, causing said lever to move on the pivotal support until it strikes the pin f13 on the dog f2, forcing the dog f2 downward, and thus allowing the spring-actuated drum to act freely, as shown in Fig. 9, and the platen-carrier will be forced forward by said spring-actuated drum.

Attached to the vibratory spacing-frame II at or near the center of the front parallel bar, 7L, is an elastic buffer, 71,7, which buffer projects below said spacing-frame, so that it strikes the main frame of the machine when the space or operating key is operated a sufficient distance to set the spacing mechanism in operation, thus indicating to the operator the end of the proper movement of the spacing or operating key to operate the spacing mechanism so as to cause the platen-carrier to move one letter-space and preventing an unintentionally too great movement of the spacing-frame.

rlhe dogf as has been heretofore described, is loosely pivoted to the lug f1 on the rod f5, and has the bifurcated arm f 15, Fig. ll, surrounding the rod f, by which means the dog` f isrigid on the forward movement of the carrier, but is iiexible in the opposite direction, and the operator can return the platencarrier any desired distance of its travel.

Attached to the sprii'ig-actuated drum by means of the hollow shaft t2 is the wheel I. On this shaft 'i2 is loosely attached the adjustable spring bell-trip and drum-stop fi, the wheel I having teeth or orifices i, the drumstop t' having projection t", which trip and stop can be moved so as to rest in any desired tooth or orii'ice of the wheel I. The adjustable spring bell-trip and drum-stop performs the double function of operating the mechanism by which the bell is rung, as will hereinafter be described, and it also acts as a stop to any further movement of the springactuated drum at any desired point. In the construction here shown one element performs both these f unetions, yet each function, if desired, can be performed by separate elements without deviating from the invention, as shown in Fig. 17, in which the second element is marked t, in which case @'19 represents the drum-stop and t' the bell-trip. On the back of the main frame of the machine is attached the bell-operator IVithin the hollow shaft i2 is the normally-idle shaft K, having iixedly attached to one end the arm k and to the other end the spring-clapper 7c of the bell L and the stop .7c-'5. The wheel Ilias upon it teeth or orifices equal in number to the number of letters the machine is capable -of writing in the extreme limit of travel of the platen-carrier.

The adjustable spring bell-trip and drumst-op t' is placed in any desired tooth or orifice of the wheel I which will be at the proper position on the wheel to engage the bell-operator when the platen-carrier is at or near the eXtreme limit of its travel. l/Vhen the wheel I is rotated by the spring-actuated drum, the adjustable spring bell-trip and drum-stop is carried with it until the projection t on said stop l1'l strikes the projection l on the under side of the bell-operator), which bell-operator normally rests against the arm 7c, the bell-operator j being so situated that if it had no pin or projection on its under side the adjustable spring bell-trip and drum-stop yL' would pass beyond 'the bell-operatorj without striking it. The striking of this projectionl of the bell-operator j causes the belloperator j and the arm 7c., against which it rests, to be carried with the adjustable spring bell-trip and drum-stop, causing the shaft K to rotate and the clapper to be drawn to the position for operation. As shown in dotted lines, Fig. 17, the bell-operator] travels in the arc of a circle, which gradually departs from IOO IIO

IIS

IZO

the are ol. a circle in which the adjustable bell-trip and drum-stop travels, until the projection l. is released [from said trip, when the l ellclapper forces the arm le back, carrying the bellsoperator back with it to its normal position and ringing' thebell. 'hen it ,is desired to prevent anyfurthcr motion at any point ol travel ol the drum, the adjustable lug lil, having the jn-ojection mi, (shown in Fig. 18,) is rigidly attached to the rim J, which rim is secured at the back of the main frame ot' the machine at any desired pointby means of the screw in', so that when the adjustable spring bell-trip and drumsstop t' in its travel strikes the projection m the motion ol the s1 ring-acluated drum ceases until the adjustable spring bell-trip and drum-stop [is returned back or the lug )l removed. The adjustable spring bell-trip and drum-stop f can be moved bz'ielmvard at will, pushing the bellwoperator,j out ot' its wayon its backward 'movement without disturbing the arm lf..

Nhen it is desired to prevent the drum l'rom returningI to its extreme initial point, a second lug M is placed on the opposite side ol' the rim. (See llig. l'T.) It' the extreme limits of movement otthe drum are used, no lugs will be necessary. \Vhen the platencarrier has reached the desired limit ol' its travel in returning toward its initial position, the necessaryv line-spaci ng is accomplished in the following manner: A plunger, N, (shown in Figs. ll, l5, and 17, having the guidepin Iu (the pin n may be dispensed with il. 1he plunger N be made rectailgular) to prevent its revolution, passes through the end oit' the platen-carrier D, also throliigh the shaft ot the ratehets O and O', preferably at the lel't-hand end, into the platen and has a spring, u', in its inner end, which normally l'orc s the plunger N outuf'ard by resting against the shoulder rr ot the plunger.

At the end ot' and attached to the platen having the plunger are the ratchets t) and O. The ratchet (l may be used alone, it desired; but the use of both ratchets O and O', said ratchets having a space between them, enables a greater width ol' paper to be used with any given size of platen.

The springpawl o normally rests in the ratchet being attached to the platen-carrier frame by a screw. The pawl o2 attached to the platen-carrier ot' the machine and connected atits outer end with the plunger by means ot' the projection e301 the plun- `ger, which projection travels in the camshaped slot o1 on the end of the pawl o2. At the inner end ol the pawl o2 the springtooth o, Then the operator in returning theplaten-carrier toward its initial position presses in the plunger N, (which is preferably accomj'ilisheffl b v resting the thumb on the thumb-piece n, shown in Figs. l and 17,) the projection os travels in the cam-shaped slot o4, acting upon the driving-pawl o2, causing the spring-tooth o5 to act upon the ratchet O, turning the platen, thus l'n'oviding lor the 'The indicator fi lille-space. This distance may be adjusted by the stop l), ivoted on the platen-carrier trame, which will limit the throw of thepawl o2 and movement of the platen. 'W hen the stop is pushed away, the plunger can be moved a greater distance, so as to cause the pawl o2 to operate upon two teeth of the ratchet, turning the platen a double distance.

"lhe stop and cam can be so constructed that three or more teeth of the ratchet may be acted upon by the driving-pawl by .increasing the throw of the pawl o2 and the movement ot the plunger, or inta-easing the extent ol the throw of the cam.

lVhen the plunger is released, the spring n forces the plunger back to its normal position, carrying the pawl o2, with its springtooth o, by means ot' the cam and projection o, back with it, and the spring of the springtooth of enables the said tooth to slide over the teeth, the pawl o preventing the platen from moving Vin the reverse direction.

The paper is held against the platen C by means ol' the pressuieroller c, and the de sired pressure is obtained tor this roller by means ol the compression-spriugs q, Fig. 14:, which are placed in recesses in the rear ends ot' the platen-carrier frame, pressing against the shalt of the j n'essure-roller at the points ot' its bearing.

In order to locate the printing-point at anyY portion ot' the platenfearrier and platen, a pointer, lt, is Vliexibly attached to the main l'rame ot' the machine, Figs. lA and 1l. It is so connected therewith that when the portion E of the main trame lll swung this pointer swings around so as almost to touch the paper on the exact line and point ol' impact, as shown in Fig. lt. The pointer R is provided with a setserew r, (said set-screw being adjustable) so that the pointer when swung around is prevented from touching the paper. The platen-earrier and platen is moved so'that it arrives atthe desired prin ting-poi nt, the pointer being normallj7 fixed at the i1n pact point ot the type. The main trame is then swung back to its position and the de sired type registered, thus obviating the necessity oit' calculating or consulting the scale. is connected to and travels with the platen-carrier, the outer end of the indicator jjiointing to the scale s, said scale being secured to the main trame and graded the desired number ol? indications equal in number to the letter-capacity ol the machine. This scale and indicator are preferably con structed as shown in Figs. 1) or 19, or `in such a manner that the indicated movement ot the platen-carrier and platen can be read when the main iframe is in its normal position, or when `the portion E ot' the main .trame E is swung upward. `When it is desired to locate the numerical position oli' one or more points on the paper, the portion E ol' the main frame E is swung upward and the carrier moved so that the pointer R rests over the desired point, at which time the nmn- IOO ITO

bered position of the desired impact point or points on the carrier may be readily read from the scale, and thus two or more positions may be located without returning the main frame to its normal position.

The ribbon-spools are constructed in the ordinary well-known manner. The ribbonspool is retained in its bearings by being held between the projection t and the st(r ndard t', Fig. 13, the projection t being secured to the main frame of the machine, and is constructed in the manner shown in Fig. 22, so that the spring-bearing t2 can have a lateral movement. The standard t is made rigidly a part of the main frame of the machine. The shaft t3 of the ribbon-spool has tapering ends which fit into the bearings. ly forcing this shaft and ribbon-spool laterally the spring-bearing t2 moves outward and the ribbon-spool shafts and ratchet-wheels can be thus readily removed from the machine and returned to their positions whenever desired.

The movement of the ribbon from one spool to the otheris accomplished and controlledin the following manner: Attached to the shaft '.l upon each ot the ribbon spools are the ratchet-wheels t. (Shown in Figs. 13 and 24.) Pawls t7, having a toothed portion, t8, rest in the ratchet-wheels. Th ese pawls are attached at their lower ends to the ribbon-operating bar U. (Shown in Figs. l. and 13.) This bar has a lip and this lip is pivoted on the standard u at u', Figs. 24 and 27, by the screw a3, but has a lateral motion upon the portion a of the screw 113, as shown in Fig. 2i, and is locked upon the-standard 1L by means of the spring-catch 1f. (Shown in Fig. 2G.) A projection, u, on said spring-catch if lits in the depressions nl in the standard u. As maybe seen, the lateral movement of' this bar U, according to the direction, causes the pawls corresponding to the ribbon-wheels to be alternately engaged or disengaged. in g-bar U extends toward -the front of the machine, Fig. 13, and is so situated that when the operator depresses any type-operatin g key both the vibratory spacing-frame and the ribbon-operating bar are forced downward, and the ribbon-operating bar, acting through its pivoted bearings upon the pawl, causes that ratchet-wheel which is connected with t-he pawl to be revolved, as shown in dotted lines, Fig. L7. The ribbon-operatinf'g` bar can be adjusted, as heretofore described, so as to cause the engagement of either pawl directly with its corresponding ratchet-wheel.

The ribbon in its travel from one ribbonspool to the other is guided and supported by means of the ribbon-supports 40, Figs. 13, 20, and l. These ribbon-supports are constructed so that the ribbon rests upon them, and they are pivoted to the main frame in such a position as to hold the ribbon at its proper place at or near the point of impact of the type. \Vhen it is necessary to reach the working parts of the machine below the ribbon, the port-ion F. of the main frame of the machine T his operatis swung upward, and the pivoted ribbonsupports are also swung up, carrying with them the ribbon, if the machine is in operation. The ribbon-supports are placed adjacent to each of the spools and are preferably connected with each other. Then the spacing-key A', heretofore described, is operated, it has no action upon the ribbon-operating bar, acting only upon the vibratory spacingframe. The spring a surrounds the standard 'tl-S and is attached to the main-frame E of the machine. lVhen the ribbon-operating bar is pressed downward, it compresses the spring a, and when the ribbon-operating bar is released the spring, being in compression, forces it back to its normal position.

The type-bar (t5, as shown in Fig. 33, may have one or more type at its lower end. This type-bar swings on the pin :11, which is riveted fast to the hanger as. This hanger as has a circular-shaped guide, x, Fig. 29, in which the type-bar swings, and is guided from its initial point of movement to its point of impact. The two walls at? of the hanger are held together by rivets or screws lVhen two or more type are used on each type-bar, it is necessary that the type on said bar which it is desired to operate shall come in such a position that it will impinge upon the platen at the proper point. This is aeoomplished in the following mann-er: The plates Z1 and b and the bar B (the hangers as are rigidly attached to the bar B) are riveted together by posts Y, forming the vibratory key-board and type-bar-carrying 'frame Z. These parts are rigidly connected with each other. This vibratory key-board and typebar-carrying frame Z is pivoted at its forward ends to the frame Z by the lugs 52,' and this frame Z is pivoted on its lower ends at 5 to the standards n of the main frame E of the machine, Figs. l, 13, 25, and 27. This frame Z is sustained at its inner end by the standard 53, a part of the main frame, to which standard the frame Z is connected by the lever .2" bythe lugI z2, said lever being pivoted on the standard 53 at by the screw z, Figs. l and 8. This frame Z has a swinging movement on these pivotal points, heretofore described, which is controlled and operated in the following manner: The lever Z1 is extended downward a distance suiiieient to give the desired extent of swinging movement to the frameZ. The connecting-link 57 is loosely riveted to the foot of said link 2A, the connecting-link having preferably a bifurcated jaw, ZS, in which the foot of the lever a rests. The connecting-link e extends a distance sufficient to give the desired movement to and from the printing-point. At the forward end of this connecting-link it is pivoted to the arm a at-zo. This arm e" is pivoted to the main frame of the machine atapoint, 512, sufliciently distant from the pivotal point' of the connecting-link 57 to give the desired movement by the arm z. The arm 5* has a forward an d backward movement on the piv- IOO IIO

otal point ,312, which conununicates, thrtmgh the counecti11g-link 27, a vibratory movement to the lever "1 and causes the trame Z to vibrate to and from the prilitingspoint. The means by which this arm '11 is caused tomove backward and toi-ward, also the means for regulating said movement, is as follows: The arm zi has a friction-wheel. at its outer end, This wheel rests within the auxiliary 'rame 5'1"', n'lade solid with the main frame. 1\ttached to said auxiliary trame are the keys t'or operating` the shitting mechanism. The wheel '11 is normally Ineventcd from rotatingI and the arm from acting by beingheld between the jaws 51 oi' the sliding stop 211, which stop has a vertical movement in the auxiliary trame '1'1. in this frame are the two shitting-key, constructed as shown, Fig. 5, and these kc have a vertical movement in the `trame ,'1 'ihe keys have a portion of their .lower end cut out, leaving a projection, 31, which rests on the top ot" a sliding stop, ,21", and its opposite edge has the projection ,2211 in contact with the lug on the sliding stop and cam-shaped end \\'hen one of the shitting-keys is depressed, the projections 31 i and "3" t'orce the sliding stop downward, re-

`leasing the friction-wheel and arm '11 and .21'. The key .31 is suspended in its trame a su t'ticient distance above the wheel '11, so that in the downward movement ot' the shifting-key the arm "1 is released trom the sliding stop bet'ore the cam-shaped end strikes the wheel E11 otl the arm 2'1". When the cam-shaped end ot the shitting-key comes in contact with t-he wheel .211, the arm .211' is caused to move baekward or i'orward on the pivotal point 512, accordingl to the direction ot the cam-sllaped end ot said shifting-key. The sliding stop '17 is retained in its normal position bythe spring 12?, to which it is attached by the pi n 221, and

its other end is attached to the adjnstingscrew otl the auxiliary frame 51'1, by which the desired tension of the spring is obtained. This spring rests in the socket: ai in the aux iliary frame of the machine. j

(bee Figs. 2, .1,

1t, and 1.13,) \Vhen the shifting-key is rehfased at'ter having shil'tcd the trame Z', the spring z2, being in tension, returns the sliding stop and the shitting-key to their normal position, 1'

and said spring "fi", aided by the spring 521', Fig. R, one end oi which is attached to the main l'ramel) and the other end to the bitu rcated end if* ot' the arm 2', t'orces the trame Z back to its normal posit-ion. ln order that when one shittingskey is (merated the other 1 is held in its normal position, a spring-button, 2'", is provided. Said spring-button .am rests in a detent, 5:1", in the shifting-key Z1, which detent is so slight that while it holds either ot' the keys normally up while the other is acting a slight, pressure will throw the spring-button 42""1 out:` ot the detent and allow the shitting-key to operate. 1d'hen Vit is desired to hold the \\'ibratory t'rame Z in a shifted position, the spring-button 2' may be forced into the detent .51 ol' the key when said key has made its full necessary movement, and said detent is oi' sufficient depth to hold said key, the shitting-trame Z', and intermediate mechanism in a fixed position.

A portion of the main trame carrying the platencarrier and platen, the platen or the platen-carrier may be shit'ted by substantially the same mechanism as that hereinbefore described; in which case the type-bar-carrying frame may be shi't'ted, as hereinbclfore described, or may be construtiftml so as to 'be rigid.

The sulrieetanatter ot' a pivoted portion ot the main `iframe is specifically reserved, as it t'orms the subject-matter of an application filed this day, said a1i1piicati i n being a divisional ap11lication ot' this application, said application being tiled Itiscembcr il-t, ISSS, and serially numbered 293,634, and relates to pivoting a portion ot the main trame to the rcmainder oi said main trame.

I do not intend to claim the combination ot' a supplementary spring with the space-key lever and letter-spzwe vibrating trame.
